Description

Technical Field

[0001] This utility model relates to a cooling device for TPE coating of carpets, belonging to the field of TPE coating technology. Background Technology

[0002] TPE is a thermoplastic elastomer with good softness, elasticity and weather resistance. Moreover, TPE materials are relatively easy to recycle. In recent years, with people paying more and more attention to environmental protection and health, carpet manufacturers have begun to apply TPE to the back of carpets to replace traditional PVC materials.

[0003] For example, in the Chinese utility model patent document with application number CN202221772127.1, a TPE multilayer carpet includes a pile yarn layer, a non-woven fabric layer and an EVA pre-coating layer arranged from top to bottom. The bottom surface of the EVA pre-coating layer is provided with an upper TPE adhesive layer and a lower TPE adhesive layer. A functional fiber layer is provided between the upper TPE adhesive layer and the lower TPE adhesive layer. The EVA pre-coating layer penetrates into each of the bottom layers up to the lower TPE adhesive layer.

[0004] During production, each layer needs to be coated and cooled sequentially. The processing temperature requirements for TPE material are quite strict in the TPE coating process. Generally, the TPE material needs to be heated to above 150 degrees Celsius during production to make it flowable and facilitate coating. During coating, to ensure better bonding between the TPE material and other layers, the temperature needs to be further increased to 195-220 degrees Celsius. After coating, to ensure the TPE portion of the carpet remains stable and its properties are cured and set, additional cooling devices must be used for cooling.

[0005] However, most existing cooling devices adopt a uniform cooling method, such as water spray cooling or air cooling. Although these cooling methods are relatively simple in process and easy to operate, their cooling effect is relatively uniform. On the one hand, a uniform cooling method cannot be targeted to the characteristics of TPE material and the actual temperature distribution after coating, resulting in low cooling efficiency. For example, for a thicker TPE layer, a uniform cooling rate may not be able to achieve the ideal cooling effect on both the inside and outside at the same time, thus prolonging the overall cooling time. On the other hand, when using a cooling method with a large temperature difference, such as directly spraying cold water onto a high-temperature TPE coating, it will damage the TPE material. TPE material has a certain degree of flexibility and plasticity at high temperatures. A sudden and large drop in temperature will cause stress concentration inside the material, especially when the TPE layer is thick. This stress concentration is more obvious and can lead to problems such as edge curling and overall deformation of the carpet, which greatly affects the quality and appearance of the carpet.

[0006] In summary, existing cooling devices can no longer meet the requirements of carpet TPE coating processes. In order to improve cooling efficiency and ensure the performance of TPE materials and the quality of carpets, further measures are needed. Utility Model Content

[0007] The purpose of this invention is to provide a cooling device for TPE coating of carpets to solve the above-mentioned problems. This device can solve the problem that traditional cooling devices have a single cooling effect and cannot guarantee the quality of carpet products after improving cooling efficiency.

[0008] This utility model achieves the above-mentioned objective through the following technical solution: a cooling device for TPE coating of carpet, including a transport platform for transporting carpets, a side plate fixed to the side wall of the transport platform, a spray pipe installed on the side plate, a spray head fixed to the bottom of the spray pipe, and a circulation assembly above the transport platform. Multiple circulation assemblies and spray pipes can be set above the transport platform according to cooling requirements. The spray pipe is used to spray out fine water droplets to cool the carpet as a whole. However, further cooling requires the participation of the circulation assembly to form a complete cooling control. The circulation assembly is used to blow cooling gas toward the carpet product, while absorbing the heat emitted by the carpet and bringing this heat into contact with the cooling pipe to neutralize the temperature difference. The circulation assembly includes a cooling pipe with a spray structure at the bottom. The cooling pipe is wrapped with a recovery cylinder, and a recovery channel is installed at the bottom of the recovery cylinder. The recovery cylinder needs to be connected to an external negative pressure container, and the gas in the negative pressure container can combine with the external cooling gas to serve as the contents of the cooling pipe.

[0009] Preferably, in order to facilitate the transportation of carpet products, the transport platform includes a support frame, and a transport belt is installed between the support frames via a rotating shaft, the rotating shaft being poweredly connected to an external power unit.

[0010] Preferably, in order to facilitate cooling of the carpet, the bottom end of the spray nozzle is open and faces the conveyor belt.

[0011] Preferably, in order to facilitate the collection of heat emitted from the carpet, the bottom of the recovery channel is provided with a flared shell, the recovery channel extends obliquely downward, and the flared shell is correspondingly arranged on both sides of the spray structure, so that the water droplets sprayed by the spray head can serve as a medium for heat transfer.

[0012] Preferably, in order to facilitate the installation of the spray structure, a bottom hole is provided at the bottom of the cooling pipe, an assembly ring is fixed at the bottom of the bottom hole, and an external threaded cylinder is fixed at the bottom of the assembly ring.

[0013] Preferably, for ease of installation and assembly, a space is left between the bottom end of the external threaded cylinder and the bottom of the recovery cylinder body, and a lower hole is opened at the bottom of the recovery cylinder body corresponding to the bottom hole.

[0014] Preferably, in order to facilitate uniform distribution of cooling gas, the ejection structure includes an installation cylinder, the top of which is threadedly installed at the bottom of the externally threaded cylinder, the bottom of which extends through the lower hole to the bottom of the recovery cylinder, and a strip-shaped distribution shell is fixed at the bottom of the installation cylinder.

[0015] The beneficial effects of this utility model are:

[0016] 1. Stable and effective cooling: This cooling device can stably and effectively cool carpet products gradually, avoiding damage to the carpet due to large temperature differences during cooling.

[0017] 2. Heat recovery and heat exchange: The spray nozzle sprays water droplets onto the carpet, and the heat can be absorbed into the recovery cylinder by the recovery channel and exchanged with the cooling gas in the cooling pipe, which reduces the difficulty of temperature control.

[0018] 3. Simple and reasonable temperature adjustment: In application, some hot air is added to the cooling pipe, and the cooling gas is adjusted to be close to the temperature of the carpet at that time according to the needs, so as to avoid drastic cooling and affect the quality of the carpet. It is very convenient to use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As shown, a cooling device for TPE coating of carpet includes a transport platform 1 for transporting and moving carpets. The transport platform 1 includes a support frame 101, and a transport belt 102 is installed between the support frames 101 via a rotating shaft. The rotating shaft is poweredly connected to an external power unit, which facilitates the transport of carpet products. A side plate 6 is fixed to the side wall of the transport platform 1, and a spray pipe 2 is installed on the side plate 6. A spray head 201 is fixed to the bottom of the spray pipe 2. A circulation assembly 3 is provided above the transport platform 1. Multiple circulation assemblies 3 and spray pipes 2 can be set above the transport platform 1 according to cooling requirements. The spray pipes 2 are used to spray fine water droplets to cool the carpet as a whole, but further cooling requires the circulation assembly. 3. To form a complete cooling control, the circulation component 3 is used to blow cooling gas toward the carpet product, while absorbing the heat emitted by the carpet and bringing this heat into contact with the cooling pipe 301, thereby neutralizing the temperature difference. The circulation component 3 includes a cooling pipe 301, with a spray structure 4 at the bottom of the cooling pipe 301. The cooling pipe 301 is wrapped with a recovery cylinder 5, and a recovery channel 501 is installed at the lower part of the recovery cylinder 5. The recovery cylinder 5 needs to be connected to an external negative pressure container, and the gas in the negative pressure container can combine with the external cooling gas to become the contents of the cooling pipe 301. The bottom end of the spray head 201 is open and faces the conveyor belt 102, which facilitates the cooling treatment of the carpet.

[0026] like Figure 2 and Figure 3 As shown, the bottom of the recycling channel 501 is provided with a flared shell 502. The recycling channel 501 extends obliquely downward, and the flared shell 502 is correspondingly arranged on both sides of the spray structure 4. The water droplets sprayed by the spray head 201 can serve as a medium for heat transfer, which facilitates the collection of heat emitted from the carpet.

[0027] like Figure 4 As shown, a bottom hole is provided at the bottom of the cooling pipe 301, and an assembly ring 302 is fixed at the bottom of the bottom hole. An external threaded cylinder 303 is fixed at the bottom of the assembly ring 302. This facilitates the installation of the spray structure 4 by personnel. There is space between the bottom end of the external threaded cylinder 303 and the bottom of the recovery cylinder 5. A lower hole is provided at the bottom of the recovery cylinder 5 corresponding to the bottom hole, which facilitates the installation and assembly.

[0028] like Figure 3 and Figure 4 As shown, the ejection structure 4 includes an installation cylinder 401. The top of the installation cylinder 401 is threaded onto the bottom of the external thread cylinder 303. The bottom of the installation cylinder 401 extends through the lower hole to the bottom of the recovery cylinder 5. A strip-shaped distribution shell 402 is fixed to the bottom of the installation cylinder 401, which facilitates the uniform distribution of cooling gas.

[0029] In use, this invention provides a stable and effective cooling device that gradually cools carpet products, preventing damage caused by large temperature differences. The spray head 201 sprays water droplets onto the carpet, and the hot air is absorbed by the recovery channel 501 into the recovery cylinder 5. The hot air then exchanges heat with the cooling gas in the cooling pipe 301. In application, some of the hot air can be added to the cooling pipe 301 to adjust the cooling gas to a temperature close to that of the carpet, thus avoiding drastic cooling that could affect the quality of the carpet.
